Sparse matrix — A sparse matrix obtained when solving a finite element problem in two dimensions. The non zero elements are shown in black. In the subfield of numerical analysis, a sparse matrix is a matrix populated primarily with zeros (Stoer Bulirsch 2002,… … Wikipedia
Matrix representation — This article is about the layout of matrices in the memory of computers. For the representation of groups and algebras by matrices in linear algebra, see representation theory. Matrix representation is a method used by a computer language to… … Wikipedia
Sparse file — In computer science, a sparse file is a type of computer file that attempts to use file system space more efficiently when blocks allocated to the file are mostly empty. This is achieved by writing brief information (metadata) representing the… … Wikipedia
Sparse array — In computer science, a sparse array is an array in which most of the elements have the same value (known as the default value usually 0 or null).A naive implementation of an array may allocate space for the entire array, but in the case where… … Wikipedia
Sparse vector — A sparse vector is a vector that is filled primarily with zero. Mathematically, a sparse vector has a low zero norm. See also * sparse matrix * Norm (mathematics) … Wikipedia

Sparse approximation — is the problem of finding a signal or vector estimate with sparseness property, that is having a small number of nonzero elements, that satisfies (approximately) a system of equations.For example, consider a linear system of equations y = Ax ,… … Wikipedia
Matrix (mathematics) — Specific elements of a matrix are often denoted by a variable with two subscripts. For instance, a2,1 represents the element at the second row and first column of a matrix A. In mathematics, a matrix (plural matrices, or less commonly matrixes)… … Wikipedia
Sparse — Eine Sparse Datei (engl. sparse file; sparse für „dünnbesetzt“, „spärlich“ oder „zerstreut“) bezeichnet eine Datei, die in einem Dateisystem sehr kompakt gespeichert werden kann, wenn sie größtenteils aus Nullbytes besteht. Inhaltsverzeichnis 1… … Deutsch Wikipedia
